i 1 Our inventionprelateslmore especially vto Ithat type 'of'l ca-'r known as .ore or slag car,.

vand which is preferably 'Vishaped in horiizontal cross section,"wherein the dumping 5 Sections or doorsform the.. bott-om portion .or apex of the V.

The objectcof the invention is toprovide:

improved mechanism forl operating the swinging'sect-ions; and also to provide means ipthatA .willy operate with the doors,.;a'nd, in 'addition toassist-ing the doors to open-to theirfullest extent, willthrow or dump the entire load beyond the perpendicular plane ofthe-oar sides,`that is, to the out-side of gthe track, as 'wi'll more 'fully appear from' thefollowing detailed description.v

the drawings:`-.l"i'gu're 1 is .a perspectiv view of a portion of our improved car, showing the operating mechanism located at one end of the car. F ig; 2 is a side elevation 'of one end of thecar. Fig; '3 isa cross sec-.

tional-view looking to-ward the right; the right hand side of. the figure being taken n on the line 2 2 of,Fig. 2 with a portion broken away, while the lleft hand. side is takenon theline 3-3 of Fig. 2., Fig. 4 is a detailview of'the operating "mechanism, F ig.` 5 is a sectional view takenon the line ofFig.4. 4 'Ou-r invention relates more especially to dump cars ofA a type adapted to carry ore or slag, wherein the side walls 1, l, and the swinging sectionsor doors 2, 2, are arranged in the-'sloping manner more clearly shownin Fig. l3, forming a 4V-shaped hopper in horizontal cross section.

The doors, which forml the lower portion ofthe hopper, are pivoted in a suitable mann er at 3, to the end wallsof the car and to 5 'the' transversely extending plate or member 4, located atv the center of the car when more than two doors 'are arranged on the same side of the car; or, when desired, the

doors may be pivoted on the side walls 1, i.

'Thesides of the car are suitably braced by .the door-supporting members 7, 7 take.

til they kha-ve been rotated by the operating vmechanism hereinafter to lbe described. A

the reinforcing `Ineznribers while the cross members at eachendofthe car and the transversely extending plate 4 are provided. with' slots or'slideways 6, through'A which These members Or shafts 7-on'e'on each side 'of the median line of the car-extend lengthwise of thehcar and bear againstthe freeffor .swinging ends ofthe doors, nor-` mally maintaining. the doors in Closed position as shown 4in the drawings. The inner faces of the end walls, and-also plate 4, are shown provided with. the horizontally ex tending studs or pins 8, 4which form' racks for the pinions 9, V'mounted on the members 7 The racks and pinions will prevent the members 7 from sliding along in the slots, holding the members against movement nn-1 mar Secured to the outer end of eachI member or shaft 7, is a star wheel or'ratchet 10; the ratchetbeing securely fastenedso. as to compel the sha-ft to rotate therewith'. Loosely mounted on each ofthe members 7, .and preferably bifurcated as shown in the drawings, is an oscillating device or lever 11, with the pawl 12 pivotally mounted between the bifurcations.' The pawls 12 engage' with the ratchets 1,0, so that. when the levers 11 are oscillated. the shafts will be rotated and compelled to move bodily along inthe slots by meansof the rack and pinion connection. Preferably mounted intermedi-- ate of the oscillating levers l1 and the body ofthe oar, arethe slidably mounted 'mem-v bers 13. 'In the construction illustrated, the

'bottoms of these members 13 are bent around upon themselves to take about the rod 14" which extends transversely of the end of the 'car and is suitably mounted in" the bracket 15 while its ends take through the dower ends ofthe corner channel ironsor' y'iframe 5, as is more Clearly shown in Fig.` 1. 'The -rod14 is bowed or bent at the center so as to have it confornIWith the direction of slots 6; and this bend in the rod will ,pre1 vent its .longitudinal movement. Of Course. any other method of mounting the rodmay be' employed, v

The shafts 7 take through the plates 13, s o that the latter are compelled to'move along on'rod 14 when the shafts are rotated and travel in the slots' ,6. Mounted on each1 of the shafts 7, between theplates -13 and;no l

the. body ofthe car, is va ratchet with which al pawl 17, mounted on each of the plates, engages.l The ratchet-1'.) and pawl 17 prevent the rotation ofthe shafts in one direction and lock the vmembers or shafts 7 iii-place.

' vMounted onl the center' sill vand underframe of the car and beneath the hopper,

and sloping downward from both 'sides of the longitudinal centerare members 18, to.

the lower ends of which are hinged, the members 19.' Members 18 form 'an inverted V-shaped portion, with its apex at the longitudinal center of the car immediately beneath the abutting ends of the doors 2, see Fig. 3. 'Phe members 18 form a chute for the dumped contents ofthe hopper when the doors 2, 2 are opened, a1.,l will direct the contents toward the sides of the track on which the 'car is located. As a permanently fixed chute is necessarily limited in length by the side line of the car, it is apparent that the materialfwill notvbe thrown a suficient distance from the track to prevent it rolling onto the track. lVe therefore provide the upwardly folding members 19, on each side 'o the median line of the car, the position with the distance between the bottoms of the' doors 2 and the freeends' of members 19- when they are in normal position.

It is apparent from this'construction,.that

when the doors 2,2, are opened, the swing-v ing sections 19 will 'immediately be permitted to drop. If, for any reason, the sections 19 should fail throuoh their own weight, to drop vdown to thelr fullest extent, they would be forced down, when the doors are opened, by the material that" has been dumped from the hopperand traveled down the permanently fi'xedchute 18.

In order to dump the load it is merely necessary to dise-ng'age pawl 17 from ratchet 16,1'when the pressure of 'the load on' the doors 2, 2,' will compel the shafts 7 to rotate along in the slots 6. -The opening of the doors 2, 2, will permit the load to fall onto the chute -18 and force the swinging sectionsl '19 of the chute downward to the limit of their downward movement and thereby,

through the pull Von the p connections .or chains'20, compel thel doors 2,2,l to Aswing open to the' fullest extent as-shown in dot` ted lines inFiig. 3. It is apparent th'atwith our improved' construction the load willbe thrown' a considera-ble distance away from the track and in view of the fact that the vver for anew bite on the ratchet.

doors at `opposite sides of the longitudinal center of the car are separately operated,'it 1s evident'thatthe load may be dumped to either side or to both sides 'of the track as desired. In order to'bring the doors and v -the swinging sections of the divert-ing, member 'or chute back to closedor normal position, the pawl 17 is thrown into engagement with the locking or holding ratchet 16,.a'nd the lever 11 oscillated. One stroke in the oscillation of the leverwill compel the ratchet '1 0, and -with it shaft Tgto rotate through. the engagement 'of pawl 12 with star wheel or ratchet 10; and the sprocket 9 on the shaft meshingwith the rack Swill compel the shaft to travel toward the longi-v tudinal center of the car. .The locking "aw'l and ratchet (17 and 16) will hold the s aftagainst -rotation-which would be caused by the Weight of the doors 2 and swinging sections 19-duringpthe return stroke of the le- This pawl and ratchet17 and 16, will-by reason of the rack and pinion connection lwith the shaftsm'aintai'n the shafts and doors in closed position against the pressure 'of the load on the doors.

le yhave shown the members or shafts 7 extendingI the full length of the car; the

same shaft const-itutinga supporting mem 9 ber for all the doors on the same side of the car, so that the opera-tion of the one. operating device will affect all fthedoors thereby supported. l
